C Exercises: Display the pattern like pyramid using the alphabet

C For Loop: Exercise-40 with Solution

Write a C Program to display the pattern like pyramid using the alphabet. The pattern is as follows :

     A 
   A B A
 A B C B A 
A B C D C B A

Sample Solution:

C Code:

#include <stdio.h>

void main() 
  {
   int i, j;
   char alph = 'A';
   int n,blk;
   int ctr = 1;
 
   printf("Input the number of Letters (less than 26) in the Pyramid : ");
   scanf("%d", &n);
 
   for (i = 1; i <= n; i++) 
	{
	for(blk=1;blk<=n-i;blk++)  
        
	printf("  ");
      for (j = 0; j <= (ctr / 2); j++) {
         printf("%c ", alph++);
      }
 
      alph = alph - 2;
 
      for (j = 0; j < (ctr / 2); j++) {
         printf("%c ", alph--);
      }
      ctr = ctr + 2;
      alph = 'A';
      printf("\n");
   }
}

Sample Output:

Input the number of Letters (less than 26) in the Pyramid : 6                                                 
          A                                                                                                   
        A B A                                                                                                 
      A B C B A                                                                                               
    A B C D C B A                                                                                             
  A B C D E D C B A                                                                                           
A B C D E F E D C B A
